2023-09-26drm/amdkfd: Handle errors from svm validate and mapPhilip Yang
If new range is splited to multiple pranges with max_svm_range_pages alignment and added to update_list, svm validate and map should keep going after error to make sure prange->mapped_to_gpu flag is up to date for the whole range. svm validate and map update set prange->mapped_to_gpu after mapping to GPUs successfully, otherwise clear prange->mapped_to_gpu flag (for update mapping case) instead of setting error flag, we can remove the redundant error flag to simpliy code. Refactor to remove goto and update prange->mapped_to_gpu flag inside svm_range_lock, to guarant we always evict queues or unmap from GPUs if there are invalid ranges. After svm validate and map return error -EAGIN, the caller retry will update the mapping for the whole range again.

2023-09-26drm/amd/display: switch DC over to the new DRM logging macrosHamza Mahfooz
For multi-GPU systems it is difficult to tell which GPU a particular message is being printed for and that is undesirable because it complicates debugging efforts. Also, the new macros allow us to enable logging for particular parts of the codebase more selectively (since we no longer need to throw everything at DRM_DEBUG_KMS()). So, for the reasons outlined above we should switch to the new macros. We can accomplish this by using the existing DC_LOGGER code to pass around the relevant `struct drm_device` which will be fed to the new macros in logger_types.h. Also, we must get rid of all instances of the DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use the DC logger there and we can simply refer to the macros directly there instead.
